DS1044 is Dallas Semiconductor's fastest 4-in-1 delay line, with four independent logic buffered delays in a single package. The device is available in a standard 14-pin DIP and 14-pin SOIC package. The device features precise leading and trailing edge accuracies. It has the inherent reliability of an all-silicon delay line solution. The DS1044's nominal tolerance is ±1.5ns and an additional tolerance over temperature and voltage of ±1.0ns for the faster delays. Each output is capable of driving up to 10 LS loads. Standard delay values are indicated in Table 1.
The DS1044 series provides four independent buffered delays in a single 14‑pin DIP or SOIC package. It features all‑silicon timing circuitry, precise leading and trailing edge accuracy, and can drive up to 10 LS loads per output.
